[1000-pipe to introduce you to the star product - hot galvanized square tube] galvanized square tube performance galvanized square tubes has good strength, toughness, ductility and welding process performance and have good ductility, its alloy layer and steel base firmly attached, so hot galvanized square tube can be cold punching, rolling, drawing, bending and other forming without damaging the coating; for general machining such as drilling, cutting, welding, cold, etc. processes. Galvanized after surface bright and beautiful, it can be directly used for engineering on demand. Category galvanized square tubes have seamless and weld points, seamless square tube is made of seamless tube extrusion. Material Carbon Q235 (A, B); low-alloy Q345 (A, B) use galvanized square tubes due to its excellent performance is often used: glass walls, power transmission tower, communications grids, water and gas transmission, wire sets tubes, houses, bridges, metal structures, power transmission, etc., in recent years has a lot to be used. Acceptance criteria galvanized square tube generally determine their eligibility appearance in the pipe outer wall surface where there is leakage of plating, pitting, white, heavy leather, air bubbles, the pan-green and the frequency of occurrence is too high, it is determined that substandard products . But in the product standard deviation of the product have a predetermined range, namely the size of "tolerance" square tube should be reasonable stacking, advanced first place (1) stacking principle requires under palletizing firm to ensure safe conditions , so that according to variety, size stacking square pass 50 * 100 different varieties of materials to be separately stacking, to prevent confusion and mutual corrosion; (2) prohibits the storage pile position near corrosive effect on steel items; (3) the bottom should be padded stack, strong, smooth, prevent moisture or deformed material; and (4) of the same material has separately by stacking storage, easy to implement the principles of advanced pre-emptive; (5) open dumps steel, the following must have wood pad or stone, pile surface is slightly inclined to facilitate drainage, and note that the material placed flat to prevent the causing bending deformation; (6) the stack height does not exceed 1.2m manual work, mechanical work no more than 1.5m , stack width not exceeding 2.5m; should leave some channel between (7) stacks and stacks, checking road is generally O. 5m, of access depending on the size of the material and transport machinery and set square pass, generally 1.5 to 2. Om; (8) the end of booster stack, if the warehouse Chaoyang cement floor, elevate O. 1m can; if it is mud, must elevate O. 2 ~ 0.5m. If it is open space, concrete floor booster O · 3 ~ O · 5m square through 60 * 120, mud face booster 0.5 ~ O. 7m 9) open dumps angles and channels should stoop to put that mouth down, I-beam shall stand up, I can not be up and groove pipe, so water rust. RHS storage warehouse to keep clean, reinforcing material conservation (1) material before storage to guard against rain or mixed with impurities, which has been exposed to rain or soiled materials to their nature in different ways wipe, such as high hardness available wire brush, low hardness with a cloth, cotton and other things; (2) the storage of materials should always check if rust, corrosion layer should be removed; (3) general steel surface cleared after the net, do not smear oil square pass 60 * 80, but high-quality steel, alloy steel sheet, thin-walled tube, alloy steel tubes, etc., required after rust inner and outer surfaces coated with anti-rust oil before storage; (4) more severe corrosion of steel, After the rust should not be long-term storage, it should be used as soon as possible. Square pass 40 * 80 | galvanized square tube (certified) | Party through 1000-by Tianjin Pipe Company Limited. 1000-Tianjin Steel Pipe Co. (www.tjqre.com) (www.tjqre.com) is Tianjin, steel leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the 1000-pipe leadership with the staff warmly welcome all inquiries negotiations to create the 1000-pipe a better future.
